Abstract

2097592 9220500 PCTABS00017 The present invention relates to a milling cutter (10) having a cutter body (12) and a plurality of replaceable tool cartridges (16) circumferentially spaced about the outer periphery of the cutter body. An adjustment mechanism permits adjustment of the tool cartridges (16) in the direction parallel to the axis of rotation of the cutter body (12). The adjustment mechanism includes an adjustment screw (52) threaded into a corresponding bore (54) in the cutter body (12). The head (56) of the adjustment screw (52) projects into an inclined throughbore (60) in the tool cartridge (16). When the adjustment screw (52) is turned, the head (56) of the screw bears against the inner surface of the throughbore (60) causing the tool cartridge (16) to be axially displaced. A locking screw (62) is tightened to secure the tool cartridge (16) in place after it has been adjusted.
